Situatie
On Windows 10, Bluetooth is a short-range networking technology that allows you to connect compatible devices (such as headphones, speakers, mice, and keyboards) to your computer wirelessly.
Although for the most part, you never need to worry about the version of the Bluetooth adapter you use. Sometimes to use a specific feature, you must have a particular version that includes a specific technology. For example, starting with Windows 10 version 1803, your device must have Bluetooth 4.0 with Low Energy (LE) support if you want to use the Nearby sharing feature to send files and links to nearby devices.
If you need to know the adapter version, you can quickly find out by checking the company’s support website or just checking your system information.
